Snipe started off small, learning to sniff out water with the highest level of chlorine from a bunch of different samples.

Motivated by a tennis ball reward system, he learned how to identify the strongest-smelling sample from series of glass pots before honing his skills even further.

"What I had to do was take the pots outside first and start doing it in different environments and then I would take the pots away and then ended up having normal tap water, pouring it on the ground and getting the dog to search that,” Stephenson said.

Now, Snipe can sniff out leaks underground, which will be a big help on the job site.
